So from what I have heard - when DS reaches Max Capacity - you can still get to your ADR. Obviously, if you are driving and can't get into the garage, this is going to be a huge problem. The actual wording on the Disney sight is less than exact. I have asked several people who have been to DS when it close to or at Max Capacity - now they were staying at Disney Resorts and taking Disney transportation - they had ADRs and were allowed to go to their dining. It would stand to reason, since the restaurants are operating at a capped capacity and should have already accounted for the upcoming reservations. If you have an ADR - I would call and check to make sure you are good. My suggestion (and a lot of those on here) is to make a alternate reservation as backup- one that is not at DS, maybe at the resort that you are staying at or somewhere close.
